Austin, Texas--April 23, 1998--Motorola (Austin) is offering a new digital signal processor (DSP) solution that they claim minimizes power consumption and offers 102 kbytes of on-chip SRAM, potentially lowering system costs for equipment that requires high-performance signal processing such as that of multichannel data.
The DSP56309 is a new member of the 24-bit DSP56300 core family of programmable DSPs that uses a single-clock-cycle-per-instruction processing engine. The new unit offers 102 kbytes of on-chip SRAM, which can enable designers to run their entire application with minimal external memory. This may reduce the board space required, lower system costs, and increase performance.
The chip may be applied to wireless base stations, remote access servers (RAS), modem pools at Internet Service Providers (ISPs), cable modems, and digital subscriber line (DSL) local loop access hardware. Functions include voice code/decode (vocoder) algorithms for speech compression, simultaneous multichannel data processing or echo cancellation in modems, and other central office equipment, as well as voice-over Internet Protocol (VOIP).
The new ultra-compact DSP56309 chip, operating at 3.3 V, is offered initially with 80 MHz operation. It provides 102 kbytes of on-chip static RAM which can be programmed in flexible block sizes in various combinations of program RAM, instruction cache, and X- or Y-data RAM. On-chip memory is essential in these applications, since the penalty for going to off-chip memory devices can be substantial. The new chip maintains code compatibility with all other DSP56300-based devices, including software, simulation models, application notes, and system development tools.
Motorola provides the Suite56 hardware and software development tools supporting the DSP56309. The software tools include a GNU C Compiler, assembler, linker, simulator, and debugger. These software tools are available on CD ROM or can be downloaded from the Web at www.motorola.com/SPS/WIRELESS/dsptools/index.htm. A hardware evaluation module (EVM) kit is also available, enabling low-cost evaluation of the DSP56309 in a Windows environment. The Motorola Suite56 tools are complemented by a range of third-party tools including a compiler and debugger from Tasking; a debugger from Domain Technologies; and an RTOS, compiler, and Integrated Development Environment (IDE) from Wind River Systems.
The DSP56309 is available now and has already been deployed at key customer sites in the United States and Europe. Parts are available packaged in a 144-pin thin quad flat pack (TQFP). In 10,000-unit quantities. The suggested retail price for the DSP56309 is $47.60.
